Find all the possible zeros of rational function.

Answer to Problem 4CYU
The simplified form of the equation
Explanation of Solution
Given information:
The given equation:
Calculation:
Consider the expression as:
Now take
Here,
The leading coefficient is
Now factor of leading coefficient is:
Now to find the list of positive rational solutions for the expression look at the factors of the constants.
That are:
Here the last two terms subtracting values from the cube of the first and want to get zero,
So as have to take the positive number, and mostly take the less than mid-way.
So take a startup with
So the value is not zero its too grater than zero.
So check with the value
To get zero:
So the value is not zero its too grater than zero.
So check with the value
To get zero:
So the value is not zero its too grater than zero.
So check with the value
To get zero:
Here got the real root, it means
Now divide the expression
So the other factor is:
Now find the factors of the expression
Simplified further either:
Or,
Thus, the simplified form of the equation
